Abstract

1329381 Polyurethane elastomers BAYER AG 1 Jan 1971 [16 Jan 1970] 48/71 Heading C3R Polyurethane elastomers having the repeating unit are prepared by reacting a polyhydroxy compound, M.W. 800-5000 with diisocyanates and using as chain extenders diamines R is H, C 1-4 alkyl, halogen, CF 3 or SO 2 Z (Z= C 1-4 alkyl) and X is F, Cl or Br. In a preferred diamine both R and X are Cl. The molar ratio of diisocyanate to chain extender plus polyhydroxyl compound may be 1À05 to 1À25. The molar ratio of NH 2 groups of the diamine to OH groups of the polyhydroxyl compound may be 0À4-1À5. Divisional Specification 1,329,382 describes and claims certain of the above diamine chain extenders.
